place to rude delineations of natural objects which expressed the name of the owner, like the Greek coins of Rhodes (a rose); of Melitaea (a bee), and were consequently looked upon as his particular mark. We have not as yet got back in Egypt to such primitive forms, but on Greek gems and coins this _type parlant_, “figured speech,” is well known. The original forms of the two great groups of Egyptian seals we have in the piece of notched reed and in the small scratched pebble; the first the true prototype of the cylinder, both in form and in mode of application; the second as clearly the original of the stamp seal. Simple as the invention of these two forms and the art of sealing may now appear, the discovery that an impression of a seal could be obtained by pressing it on clay or other plastic substance was nevertheless one of the most momentous that has yet been made, and the seal-impression furthermore suggested the idea of decoration in bas-relief. From the invention of the simple seal to the complex printing-press with its moveable types appears a long way to travel, but that we have the germ of this great invention in the simple seal is obvious when we come to think of it. The old Egyptian or Babylonian who first took an impression of his signet on a lump of plastic clay, had discovered the principle of printing, though it took the human mind many hundred years before the next great step was made, that of smearing some black or coloured substance upon the seal and taking a “print” of it on plaster, as in the tomb of Thothmes IV (_circa_ B.C. 1400), and in ink on a papyrus of the Ptolemaic age. 4.
